Final Flourish

A brutal yet precise move performed by gifted bladesingers, forgoing defense for a swift end to a confrontation.

When you hit with an attack, you may choose to deal additional damage equal to Xd8, where X is your proficiency bonus plus 1. You may only use this ability if you started your turn with Bladesong active. Bladesong ends immediately, and you can’t activate it again this encounter.
